Not much has changed from the initial release of Safari 7.1 and 6.2 earlier in July, but Apple is asking testers of the most recent "Beta 2" versions to focus on password and credit card autofill tools.

The first builds of Safari 7.1 for Mavericks and Safari 6.2 for Mountain Lion brought WebGL-powered 3D rendering to Apple's browser and WebKit engine features like IndexedDB, JavaScript Promises and CSS Shapes and Compositing. Along with Apple's upcoming Safari updates, the WebKit and WebGL modifications seen in today's betas are expected to see wider adoption in OS X 10.10 Yosemite and iOS 8.

Developers are once again asked to concentrate on "general website compatibility," including subpixel rendering and CSS model getters, the latter of which may render content differently depending on design constraints. Finally, Apple requests testing of Safari extensions.
